Cannot build APK or run project on android device

TooMuchJava · December 26, 2018, 9:49pm

I used the old sdk manager that works with JME, enabled android deployment, and turned off compile on save. No .APK is generated in the dist folder, and when I try to run using the “Android Device” configuration, i get this message:

Target "run-android" does not exist in the project "Crushed". 
BUILD FAILED (total time: 0 seconds)

My guess is I need to add a new target to the build file, but I have no idea what to put there.

I don’t think this matters, but I’m targeting Android 7.0(API 24 i think)

Did you try this boilerplate? It may be still working: JMonkeyEngine Android Template

TooMuchJava · December 26, 2018, 10:18pm

Error window using bootmonkey: Project folder must not be empty.
Any ideas?

Also, would I have to create a new project with thisand copy my src and assets over?

I was able to create a JME Android app recently. Best advice I have is to use Android studio and use the JME Android Harness for the MainActivity.

There wasn’t much special in the JME version of the game other than simple controls.

Process:

Make JME Game

Source is above.

Make New Android Project
Reference compiled Game.jar and all libraries you used
Edit Manifest and MainActivity

My Manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.bigbawb.maniacmaze">

    <application
        android:versionCode="1"
        android:versionName="1.0" >
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme"
        >

        <activity android:label="@string/app_name" android:launchMode="singleTask" android:name="MainActivity" android:screenOrientation="landscape">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>

    </application>>

</manifest>

My Main Activity:

package com.bigbawb.apps.myapplication;

    public MainActivity() {
        this.mouseEventsEnabled  = true;
        //splashPicID = R.drawable.splash;
        // Set the application class to run
        appClass = "mygame.Main";
        // Try ConfigType.FASTEST; or ConfigType.LEGACY if you have problems
        //eglConfigType = ConfigType.BEST;

        //mouseEventsEnabled = true;
        // Set the default logging level (default=Level.INFO, Level.ALL=All Debug Info)
        LogManager.getLogManager().getLogger("").setLevel(Level.INFO);
    }

    @Override
    public void onCreate(Bundle bundle) {

        super.onCreate(bundle);

        if (app != null) {
            AndroidManager androidManager;
            app.getStateManager().attach(new AndroidManager());
            androidManager = app.getStateManager().getState(AndroidManager.class);
            androidManager.setFilePath(getFilesDir().toString());
        }

        int androidVersion = android.os.Build.VERSION.SDK_INT;


        if (androidVersion > 10) {

            AdView adView;

            adView = new AdView(this);
            adView.setAdSize(AdSize.SMART_BANNER);
            adView.setAdUnitId("XXXXX");
            adView.buildLayer();

            LinearLayout ll = new LinearLayout(this);
            ll.setGravity(Gravity.BOTTOM);
            ll.addView(adView);
            addContentView(ll, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

            AdRequest adRequest = new AdRequest.Builder()
                    .build();

            // Start loading the ad in the background.
            adView.loadAd(adRequest);
            adView.bringToFront();
            adView.requestFocus();

        }

    }

    @Override
    public boolean onTouchEvent(MotionEvent e) {
        
        return true;
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        System.runFinalization();
        android.os.Process.killProcess(android.os.Process.myPid());
    }

}

Should run your JME game just fine.

I seem to have hit problems using the lighting shader. Is there another way to achieve this? My game 100% depends on shadows(the things trying to kill you are way above you, it’s the warning system.)

Album has comparison of with/without DirectionalLightShadowRenderer(so you can see why I need it.)

Edit: Could I copy the PostShadow.frag file and just rename the variable on all occurances?
Edit#2: My phone also seems to ignore app.settings.setFrameRate(30);

I’ve always used unshaded materials when doing JME applications. Can’t help you when using shaders or lighting unfortunately.

TooMuchJava · December 29, 2018, 2:52am

All I should need to do is copy the entire code of DLSR and ASR, and change the location of the post processing shader in the ASR to my new one which is exactly the same, but without the conflicting variable name.

P.S. How do you manage any silver-like colors using Unshaded materials?

TooMuchJava · January 1, 2019, 5:02pm

Well I couldn’t find ‘sampler2DShadow’ in PostShadow.frag, PreShadow.frag, BasicPostShadow.frag, or Phadow.vert(I was getting desprate), so I assume it’s in

#import "Common/ShaderLib/Shadows.glsllib"
#import "Common/ShaderLib/GLSLCompat.glsllib"

Any Ideas/workarounds? I guess I could always make some bitmaps and render them on the ground as a shadow.
FPS Fix:

define counter as an integer

new Thread(() -> {
         while (counter > -1) {
         try {
             Thread.sleep(1000/30); // MY Framerate(or updaterate I guess) is 30fps
             counter++;
         } catch (InterruptedException e) {}
         }}).start();

In your AppState’s init method.

public int updateCounter() {
     int c = counter;
     counter = 0;
     return c;
 }
 @Override
 public void update(float tpf) {
    int uc = updateCounter();
    for (int i = 0; i < uc; i++) {
        // Your update stuff that needs to be repeatedly fired(game logic, entity updates, Etc...)
    }
    //Your updates that don't need to be repeatedly fired(UI, Guis, Hud, Etc...)
}

counter = -2; in cleanup method
